`user_database_init(load_result)` has no credential input. Missing storage is persisted empty; `user_database_recover_empty()` is the unavailable-only destructive recovery API. Valid v1 user bytes load without rewriting or account changes. The private `v1_admin_marker` retains its byte position and is derived from administrator count during mutations; it is not a public bootstrap state, new role or schema change. No user migration/bootstrap/synchronization API remains.
`web_security` owns TLS only. A private reader validates 1,392-byte v1 `web_sec/material`, copies exact key/certificate DER, fingerprint and generation into 1,340-byte v2, commits, then publishes. Temporary v1 credential-bearing input is wiped; no public legacy credential type/getter/rotation remains. Malformed/unknown records and read/validation/commit failures fail closed, with no fallback regeneration or overwrite of rejected records. Missing material may be generated; explicit reset replaces TLS only. Downgrade to v1-only firmware is incompatible. Logical NVS replacement is not secure flash erasure. Contracts/evidence: [legacy compatibility](../legacy_credential_removal.md).
